Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a radial high-efficiency filtration device for depolymerized oil of high molecular weight organic matter. Background Technology

[0002] Waste tires need to be recycled and reused. Currently, continuous depolymerization and oil extraction using a gaseous heat carrier is a new, highly efficient, and environmentally friendly process for treating waste tires. It utilizes self-generated gas, heated through circulation, as a heat carrier to provide heat for the continuous depolymerization of waste tires. This process allows for the complete recycling of waste tires, producing depolymerized oil, coarse carbon black, steel wire, and depolymerization gas. While the tire depolymerized oil can be used directly, it inevitably contains impurities such as carbon black, metal fragments, and moisture from the tires themselves. To improve the quality of the depolymerized oil, it must be filtered and purified.

[0003] Currently, traditional depolymerized oil filtration devices typically employ vertical pressure filtration, where the depolymerized oil flows downwards under gravity and is filtered through a filter medium. However, this filtration method suffers from limitations such as limited filtration area and low filtration efficiency, making it difficult to meet the demands of large-scale industrial production.

[0004] Therefore, this application provides a radial high-efficiency filtration device for depolymerized oil of high molecular weight organic matter to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a radial high-efficiency filtration device for depolymerized oil of high molecular weight organic matter, so as to solve the problem that the existing filtration devices adopt vertical pressure filtration, which makes it impossible to meet the high-efficiency filtration requirements of depolymerized oil on a large scale by using only the bottom filter layer.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A radial high-efficiency filtration device for depolymerized oil of high molecular weight organic matter includes:

[0008] A filter cartridge for holding depolymerized oil containing high molecular weight organic compounds, and an opening is provided at the top of the filter cartridge;

[0009] A filter cylinder, wherein multiple coaxial filter layers are arranged around the inner wall of the filter cylinder;

[0010] The filter screen is vertically inserted into the filter cylinder, and the filter screen divides the interior of the filter cylinder into an inner and outer inlet oil collection area and an outlet oil collection area, and the top opening of the filter cylinder is connected to the top of the inlet oil collection area.

[0011] The bottom of the filter cylinder is equipped with a feed pipe that connects to the bottom of the inlet oil collection area and an oil outlet pipe that connects to the bottom of the outlet oil collection area.

[0012] Optionally, the top opening of the filter cartridge is fitted with a top cover, and a vertical oil inlet pipe is fixed in the middle of the top cover, with the lower end of the oil inlet pipe extending into the inlet oil collection area.

[0013] Optionally, a plurality of limiting baffles are fixedly arranged around the inner wall of the filter cylinder, the limiting baffles abutting against the outer side of the filter cylinder to form support, and a limiting ring is fixedly arranged around the bottom surface of the filter cylinder, the limiting ring abutting against the inner side of the filter cylinder to form a limit.

[0014] Optionally, the limiting baffle is an arc-shaped structure adapted to the inner wall of the filter cylinder and the outer side of the filter screen cylinder.

[0015] Optionally, a plurality of the limiting baffles are evenly distributed on the inner wall of the filter cylinder and arranged in layers.

[0016] Optionally, the filter cylinder is a multi-layer cylindrical structure, with each layer of cylinder serving as a filter screen. The pore size of the filter screen gradually decreases from the inside to the outside. A handle is connected to the top of the filter cylinder, and spacers are fixed between each layer of filter screen to form multiple chambers for setting the filter layers.

[0017] Optionally, the filter layer includes at least three layers, including a coarse filter layer, a fine filter layer, and an outer filter layer arranged sequentially from the inside to the outside along the circumferential direction.

[0018] Optionally, the filter media of the coarse filter layer includes 5-10 mm rubber particles, the filter media of the fine filter layer includes 3-4 mm activated carbon particles, and the filter media of the outer filter layer includes one or a mixture of 7-8 mm rubber particles, ceramsite, and gravel.

[0019] Optionally, the oil outlet pipe is equipped with a ball valve and a pressure gauge. The ball valve is used to control the outflow of the filtered depolymerized oil, and the pressure gauge is used to display the outlet oil pressure.

[0020] Optionally, the bottom of the filter cylinder is provided with several support legs, which are evenly distributed around the bottom of the filter cylinder to support the entire filtration device.

[0021] Compared with the prior art, this utility model has at least the following beneficial effects:

[0022] The above scheme employs a multi-layer vertical cylindrical structure, using a filter screen to divide the interior of the filter cylinder into an inlet oil collection area and an outlet oil collection area. This allows the depolymerized oil to flow radially outward from the inner wall of the filter screen, passing sequentially through a coarse filter layer, a fine filter layer, and an outer filter layer. Compared to traditional vertical pressure filtration, this radial pressure filtration method significantly expands the filtration area for the depolymerized oil, enabling it to make more thorough contact with the filter medium during flow, thereby significantly improving filtration efficiency and meeting the needs of large-scale industrial production.

[0023] In the above solution, the filter cylinder's structure and plug-in installation method facilitate the vertical insertion and removal of the filter cylinder, making it easy to replace the coarse filter layer, fine filter layer, and outer filter layer inside the filter cylinder, thus simplifying later maintenance and making it convenient to use.

[0024] In summary, this device not only has better filtration efficiency, but also makes it easy to disassemble and replace the filter layer, resulting in good overall performance. Attached Figure Description

[0039] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a radial high-efficiency filtration device for depolymerized polymeric oil, comprising: a filter cylinder 1 for holding depolymerized polymeric oil, the filter cylinder 1 having an opening at its top; a filter screen cylinder 2 having multiple coaxial filter layers arranged around its inner wall; the filter screen cylinder 2 being vertically inserted into the filter cylinder 1, wherein the area inside the filter screen cylinder 2 within the filter cylinder 1 is an inlet oil collection area 4, and the area outside the filter screen cylinder 2 is an outlet oil collection area 3, and the top opening of the filter cylinder 1 is connected to the top of the inlet oil collection area 4; the bottom of the filter cylinder 1 is equipped with a feed pipe 401 connecting to the bottom of the inlet oil collection area 4, and an oil outlet pipe 301 connecting to the bottom of the outlet oil collection area 3.

[0040] This radial high-efficiency filtration device for depolymerized organic oil works by introducing the depolymerized oil into the inlet oil collection area 4. The oil then permeates radially outward from the inlet oil collection area 4 on the inner wall of the filter cylinder 2, undergoing multi-layer filtration to remove impurities of different particle sizes before entering the outlet oil collection area 3 on the outer side of the filter cylinder, thus achieving radial gradient filtration. The discharge pipe 401 is used to discharge residual depolymerized oil and impurities from the filter cylinder 1 after filtration is complete.

[0041] This radial pressure filtration method greatly expands the filtration area of ​​the depolymerized oil, allowing it to come into more full contact with the filter medium during flow, thereby significantly improving filtration efficiency and meeting the needs of large-scale industrial production.

[0042] In summary, this device effectively improves filtration efficiency and quality by changing the filtration area from the limited cross-section in traditional gravity filtration to an expanded circumferential side surface. At the same time, it facilitates the disassembly and replacement of the filter layer, resulting in good overall performance.

[0043] Specifically, the filter cylinder 1 has four support legs 101 at its bottom, which are evenly distributed around the bottom of the filter cylinder 1 to support the entire filtration device. The top of the filter cylinder 1 has an opening and is secured to a top cover 6 by bolts or clips. A filter screen cylinder 2 is vertically inserted into the middle of the filter cylinder 1. Multiple coaxial filter layers are arranged around the inner wall of the filter screen cylinder 2, dividing the interior of the filter cylinder 1 into an inner and outer inlet oil collection area 4 and an outlet oil collection area 3. The top opening of the filter cylinder 1 communicates with the top of the inlet oil collection area 4. A vertical oil inlet pipe 7 is fixed to the middle of the top cover 6, with its lower end extending into the inlet oil collection area 4, allowing the depolymerized oil from high-molecular-weight organic compounds to be introduced into the inlet oil collection area 4. Additionally, the bottom of the filter cylinder 1 is equipped with a discharge pipe 401 connecting to the bottom of the inlet oil collection area 4 and an outlet pipe 301 connecting to the bottom of the outlet oil collection area 3. The oil outlet pipe 301 is equipped with a ball valve and a pressure gauge. The ball valve is used to control the outflow of the depolymerized oil after filtration, and the pressure gauge is used to display the pressure of the outlet oil circuit. The pressure change can be used to determine whether the filter layer is blocked. For example, a sudden increase in pressure indicates that the filter layer is blocked.

[0044] like Figure 3 and Figure 4 As shown, the filter cylinder 2 has a multi-layer cylindrical structure, with each layer being a stainless steel filter screen. The pore size of each stainless steel filter screen gradually decreases from the inside to the outside. A handle 201 is connected to the top of the filter cylinder 2, and spacers 202 are fixed between each layer of stainless steel filter screen to separate and fix the individual filter layers, thus forming multiple chambers within the filter cylinder 2 for housing the aforementioned filter layers. Specifically, a handle 201 is also hinged to the inner wall of the top of the filter cylinder 2 for easy lifting and insertion / removal of the filter cylinder 2.

[0045] The filter layer comprises three layers, specifically a coarse filter layer 8, a fine filter layer 9, and an outer filter layer 10 arranged sequentially from the inside out along the circumferential direction. In specific implementations, the filter media of the coarse filter layer 8 may be, but is not limited to, 5mm rubber particles, for preliminary filtration of large particulate impurities in the depolymerized oil; the filter media of the fine filter layer 9 may be, but is not limited to, 3mm activated carbon particles, for further adsorption of small particles and harmful substances in the depolymerized oil; the filter media of the outer filter layer 10 may be, but is not limited to, 7mm rubber particles. In other embodiments, the outer filter layer 10 may also be one or a mixture of several types of ceramic granules or gravel of the same particle size, serving as the final filtration and purification layer. The ceramic granules can be flowerpot balls.

[0046] Cooperate Figure 2 and Figure 5As shown, several limiting baffles 5 are fixedly arranged around the inner wall of the filter cylinder 1. The limiting baffles 5 abut against the outer side of the filter screen cylinder 2 to form a support. A limiting ring 501 is fixedly arranged around the bottom surface of the filter cylinder 1. The limiting ring 501 abuts against the inner side of the filter screen cylinder 2 to form a limit. The limiting baffles 5 are arc-shaped structures adapted to the inner wall of the filter cylinder 1 and the outer side of the filter screen cylinder 2. The several limiting baffles 5 are evenly distributed on the inner wall of the filter cylinder 1 and are arranged in layers to ensure the uniformity of the support.

[0047] The working principle of the technical solution provided by this utility model is as follows:

[0048] This radial high-efficiency filtration device for depolymerized organic oil operates by introducing the depolymerized oil into the inlet oil collection area 4 through the inlet pipe 7. The oil then permeates radially outward from the inlet oil collection area 4 on the inner wall of the filter cylinder 2, passing sequentially through the coarse filter layer 8, the fine filter layer 9, and the outer filter layer 10. After removing impurities of different particle sizes, the oil enters the outlet oil collection area 3 on the outer side of the filter cylinder, achieving radial gradient filtration. This radial pressure filtration method significantly expands the filtration area of ​​the depolymerized oil, allowing for more thorough contact between the oil and the filter medium during flow, thereby significantly improving filtration efficiency and meeting the needs of large-scale industrial production.

[0049] Meanwhile, by inserting the filter cylinder 2 into the filter cylinder 1 in a plug-in manner, and using the limiting baffle 5 and the limiting ring 501 for limiting, it is easy to disassemble and assemble the filter cylinder 2, and easy to replace the coarse filter layer 8, fine filter layer 9 and outer filter layer 10 inside the filter cylinder 2, which is beneficial for later maintenance and convenient to use.

[0050] In summary, this device effectively improves filtration efficiency and quality by changing the filtration area from the limited cross-section in traditional gravity filtration to an expanded circumferential side surface. At the same time, it facilitates the disassembly and replacement of the filter layer, resulting in good overall performance.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
